Clone() does not clone modifiers (via Modify()) to the new query

[liamg]

• The issue is present in the latest release.
• I have searched the issues of this repository and believe that this is not a duplicate.

Current Behavior 😯

When I use Modify() on a query, and then Clone() that query, the cloned query does not include any of the modifiers.

Expected Behavior 🤔

The clone and the original should be identical, including changes made by Modify()

Steps to Reproduce 🕹

Steps:

1. Create a query
2. Make a change via Modify() e.g. join another table.
3. Clone() the query.
4. Compare the two queries - the original will have the modification, the clone will not.
